Sandra Bullock and son Louis are looking skeletal

Halloween came early for Sandra Bullock and her son Louis over the weekend.

The 49-year-old actress slipped into character as a ghoulish skeleton dressed in a gown to match her three-year-old son's spiffy skeleton costume.

Bullock also wore a face full of makeup - and not the glamorous kind - to pull off her horrific look, while her son had a pair of detachable wings.

According to Us Weekly, the single mom got into the scary spirit on Saturday to escort Louis to a Halloween party in Los Angeles.

Although the tyke probably picked up on the suspicious amount of cameras trailing after him and his mom, Bullock's told CNN previously that her little one "has no idea" just how famous she is.

"I'm simply the mom who makes the lunch, drives to school, finds where the toys are, washes the clothes, and I'm here to play," Bullock said. "And that's all I should be."
